4.3 do_change_speed

Hello guys.
Can someone help to understand innovation in AP 4.3 ?

  • allow reset to default airspeed using mission item DO_CHANGE_SPEED

Wasn’t it like that before?

Replying for completeness.

Before there was no way to reset to parameter value of TRIM_ARSPD in a mission. You had to have a GCS or Lua script read the parameter value and update the mission command. So in cases where the misison says, “Go faster and then return to normal speed” the normal speed was determined by the mission item speed and not the parameter airpseed.
